An-PURIFIER hun TEMPERATURE-REGULATOR.

Specification of Letters Patent. @attempted Netw., 23, 1915.

Application filed July 25, 1914:. Serial No. 853,155?.

To all whom t may concern:

Be itknown that l, GEORGE SINGLAIR, a citizen of the United States, residing at St. Pauhin the countyof Ramsey and State of li/linnesota, have invented a newand .useful Improvement in AirPuriiiers and Temperature-Regulators, yof whichthe following isa specification. I

r1`he object of my invention is to cleanse, meisten and deliver purified and moistened air at any desired predetermined temperature for use. .Y

The invention is especially designed for use in making butter although there are many uses to which this air can be applied. lt will be understood that while the cream is ripening,'to obtain the best flavor for the butter the cream must be kept-at a certain temperature such as 52 degrees or as may be desired. `By the use of my device air can be purified and delivered into the .cream while ripening at they desiredtemperature and can be maintained at a uniform temperature for any desired period regardless of the temperature of the airl before entering the improved device. j

1n the drawings with which l have illustrated my invention and which form part of the specification, Figure 1 is a sectional ele'- vation illustrating my device; Fig. 2 is an end elevation of Fig. `1 and Fig. 3 is a longitudinal section of a detail of my invention.

In the drawings A indicates a water tank of ordinary construction which is mounted on a frame 2 and has `an inlet for water through pipe 3, which is closed by a valve 4C. At the bottom of the tank A is a suitable drain pipe 5, which is closed by a valve 6. The tank A. has a safety valve 7 of ordinary construction and a pressure gage 8 which indicates the pressure at which the air is maintained in the tank.

Above the tank A. and mounted on the frame 2 is a smaller water tank B in `which .is centrally located an air pressure tank C. Air is forced into the tank C at one end through a pipe 9, which is connected to a blower or air pump, and a suitable valve 10 in said pipe of ordinary construction pre vents air from passing back out of the tank C through the pipe 9. The tank C may be .fitted with a safety valve of ordinary construction (not shown) which prevents any excess pressure in the tank.

.in size with the openings 19.

Theair is automatically passed from the tank Cinto .the tank A through pipes 12, 13,

14 and the valve 15 which connects the pipes 12 and 13 and is constructed similarly to the .ordinary .safety valve beingset at the de- -siredescaping pressure. rthe-pipe 13 passes l.through a water tank D which has a water intake pipelt in its bottom and an outlet 17 atthe top kwhich connects with the tank B, the tank Bhaving anoutlet 18.

r1`he pipe 14 is securedin'the tank A in any suitable manner and has perforations 19 which are opened and closed by a movable sleeve 2O (see Fig. 3) which i'its inside the pipe 14: and has openings 21 corresponding is operated by a handle 22 which is connected .thereto by a threaded stein 24: and a swiveled joint QS of ordinary construction. When the handle 22 is turned the sleeve 2O is drawn back and forth in the pipe 11 and the openings. 19 and 21 are brought to correspond thereby allowing the air to pass from the pipe 14 into the tank A (as illustrated in Fig. 3 where the openings 19 are shown in partly closed position). This air .entering the tank under pressure raises the pressure maintained in the tank. A graduated dial` 2o is fixed between the tank A and vthe handle 22 'and an indicating finger 2G adjustably fixed on the stem-24: serves to indicate the open and closed positions of the openings 19 in the pipe 14 Thus the size of the openings can be readily adjusted as desired to increase or decrease the flow of air in the tank A.;

In the operation of my device when it is desired to obtain a flow of cold air, well water or cold water is circulated through the intake pipe 16 and tank D thence into the tank B thro-ugh the pipe 17 and out of pipe 18 and the tank A is filled about two thirds full of cold water. Then the valve 1 5 is set at the desired escaping pressure and air is blown or pumped into the tank C through the pipe 9 where it is compressed and cooled by the flow of water through the tank B. As the air passes onward it comes into contact with colder and colder radiattwo or three degrees.

Water which puriies it and out of the pipe 27 to the cream tanks, the air being injected into the cream in the usual manner. It will thus be noted that as the-air is cooled Aunder pressure, when it is released to normal pressure it will absorb heat and 'by careful adjustment of my device it can be delivered at a Vuniform temperature 'in an economical wav.

thermometer 28 in tank A assists the operator in adjusting my ydevice to the 'desired temperature. It 'is obvious that the air can be cooled. more orless as desired by the adjustment of my device.V

It is an important feature that it is not necessary'touse ice in the water in tank Ato keep the temperature of the water downwhen a uniform flow of cool air is desired, and that the flow of air can be delivered at the same temperature for a long period without renewing the water in tank A Vand only changing the temperature of the same Thus infoperation the water is renewed inthe tank A about once a day in order to'purify the air from dust, etc., but not forV the purpose ofy cooling the air. Y f

I-n accordance withthe patentstatutes, I have described the lprinciples of operation of VAmy invention, together with the apparatus which I now consider tolrepresentf' the best .embodiment thereof, but lI desire to have it understood that the construction shown is only illustrative and-that'the'invention can be carried out by other means and applied to uses otherthan'those Vabove set forth within the scope of theifollowing claims.

Having described my invention, what I claim as new and'desireto-protect by Letters Patent is l. In an air purifier: andtemperature regulator, an air tank adapted to receive air under pressure, means for cooling compressed air in said tank, a water tank communicating therewith, a perforated pipe eX- tending across the bottom of said water tank, a valve for automatically releasing the air v1n said compressing tank at a reduced pressure through said perforated pipe and into the water in said water tank to purify the same.

2. In an air purifier and temperature regulator, an air supply tank, means for cooland delivering means a cooling medium of constantly decreasing temperature in a plurality of steps.

4. In a device of the class set forth, an air supply tank, a water `iacket about said tank through which wat-er is adapted to be circulated, a valve adapted to automatically releaselthe air in said tank at a predetermined pressure and means forpassing the air so released from said tank through a volume of water topurify said air.

5. -In Ia device of the class set forth, an air supply tank, meansfor cooling the air in saidl tank, airadjustable valve for automatically releasing the air from said tank at a predetermined pressure, a watertank communicatingvwith said air tank adapted to contain a volume of water and a perforated pipe in` said -water tank adapted to distribute air fromsaid valve into said water to purify said air.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

GEORGE SINCL'IR.
